Application filed October 8, 1913. serial to. 794,133.

To all whom it may concern:

Be it known that I, Roy N. DIKE, a citizen of the United States of America, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Spring- Doubletrees, of which the following is a specification.

My object is to provide a double-tree with a spring attachment that will save the horses from being worn and injured by sudden stops when a wheel of a wagon strikes or drops into a hole or rut thereby stopping the wagon suddenly, causing a sudden jerk and strain on the shoulders of the horse, which strain is repeated when the horse again starts forward to pull the wheel out of the hole or rut. I overcome this by the attachment of a spring which, when the wheel drops into a hole or rut, gives, and relieves the horses shoulders from a sudden joltor jerk; and, when the horse starts on, the spring gives at the first pull of the horse relieving the horse from the strain, which ordinarily occurs under the circumstances described, and enables the horse to 1 go on without unnecessary strain.

I accomplish my ob ect bythe mechanism illustrated in the accompanying drawings, in which-- Figure l is a top View of the tongue of a wagon, and a double-tree with a flat spring attached, and two spring-trees each connected with the double-tree, an end of the fiat spring and a swin le-tree; Fig. 2 is a cross section of the double-tree, showing a clevis and spring-tree; Fig. 3 is an enlarged detail view of the Hat spring, showing the manner of securing the same to the double-tree; Fig.- 4 is a sectional view of Fig. 3; Fi 5 is a detail of a joint of a spring-tree an spring; Fig. 6 is a top view of Fig. 5; Fig. 7 is a top view showing the combination of three s'wingle-trees attached to a double-tree provided with flat springs; Fig. 8.is a top view showing the combination of four swingletrees attached to a double-tree with spiral springs, and Fig. 9 is a detail of said spiral spring showing the manner of securlng the same to the double-tree and in a channel in the end of a spring-tree.

Similar letters refer throughout the several views to corresponding parts.

A represents the tongue of a wagon.

B is the double-tree of a wagon which is constructed of lengths adapted for use with the swingle-tree may two, three or four swingle-trees C C havln'g hooks C C to engage with tugs, as shown in Figs. 1,7 and 8. It may also be made a length adapted to one swingle-tree only.

D is a hook and F is a elevis forming connection between a swingletree C and a spring-tree E. I I are flat clevisesconnected at one end with bolts in said springtrees and at the other end connected with the double-tree. I

7'. f are holes in the spring-tree by which be regulated for heavier or lighter draft.

As shown in Fig. 7, the center swingletree is connected with the spring-tree E bymeans of a bolt f working pivotally to enable the middle horse to Work on bothof the oppositely placed flat springsJ J.

H is a flat piece of iron gained into the double-tree to prevent wear, as shown in Fig. 3. Said springs are attached to the double-tree, preferablyrby iron clamps J 'J which grasp around the spring and double-tree; said clamps each have a hole j, as shown by dottedlines in Fig. 4, to receive a lug j, welded on the spring, as shown in detail in Fig. 3. The spring is fastened to thespring-tree by a bolt 6, as shown in Figs. 5 and 6. p

b is a late on the double-tree to receive a bolt an prevent wear, as shown in Figs. 7 and8. p

K is a spiral spring, shown in Fig. 8 and in detail by Fig. 9; this spring may be substituted for the flat spring, if preferred. Said spiral spring is held in place at the bottom bv'a plate K of iron or steel which is screwed to the double-tree, the spring being bolted on plate K as shown in Fig. 9. Spring-tree E is provided with a channel E in which the top of the spring is bolted, as shown in detail in said Fig. 9.

In the foregoing description and in the drawings I have shown two forms of springs,-a fiat spring and a spiral spring. Either form may be used each accomplishing the same purpose and the form in itself swingle-trees.

of more swingle-treesforward thereof,

short spring-trees equi-distant between said double and swingle-trees having spring and flat clevis connection with the double-tree and hook and clevis connection with the able, a clevis and hook on said swing1e-tree to engage with said holes, a spring at the other end. of said spring-tree said spring be- 15 ing seated on the front of said double-tree and a fiat straight clevis forming connection between said dohble-tree and the central part of said spr ng-tree.

In testimony whereof I aflix my signature 20 in presence of two witnesses.

ROY N. DIKE.
